In this article we argue for the importance of building critical communities as an integral, yet neglected, aspect of education for social justice. We begin by defining critical communities and by describing goals and vision for social justice education. We then explore how community is discussed in the education literature, limitations and challenges of calling for community, and images of critical communities in social justice work. We end by exploring the role that individuals can play in nurturing and enabling social justice efforts, offering some strategies to promote community building within and beyond higher education.
